get hours of current date in a variable like: 

let hour = Calendar.current.component(.hour, from: Date())

Now pass this to your switch statement and change the image.

Your Swift Statement will be like this (Change images as per your need):

switch hour {
    case 1...6: 
        yourImageView.image = homepageNight
    case 7...18: 
        yourImageView.image = homepageNight
    default:
        yourImageView.image = homepageNight
 }

If you have any doubts please comment.

Happy to help!

If you only need to get the current hour and know if its AM or PM, you can use something like this:

let formatter = DateFormatter()
formatter.dateFormat = "hh a" // "a" prints "pm" or "am"
let hourString = formatter.string(from: Date()) // "12 AM"

So, after this you only need to apply your correct image bay the hour getting the string value.
